police responding by firing shots in the air, firing tear gas in the air. as i mentioned before, some small buildings, check posts were set on fire. police telling us that eight of their officers were injured, but we can't repeat enough there's 180 million people here in pakistan. a small fraction, 1,500 here in islamabad, protested. the pictures are dramatic, and it's this mirpt that's going to make the headlines, unfortunately. >> so, reza, what's the motivation here? is it back to that u.s.-made video, or is it related to the cartoonist in the french publication? >> my impression is that most of these protesters are still angry about the movie, and they don't even know about the cartoon. what's remarkable is a week ago we contacted some of these hard line religious groups. they didn't even know about the movie then. it was only when the publicity came out that they were aware of it and these protests came out.
